Hello!
Here is what i've got so far:
I needed to put my ISO file (iDeneb, iAtkos, or any other distros) to a 8GB USB Disk.

Now it boots, really fast. I reach the installer. On iAtkos (Snow Leopard), it doesn't detect my HDDs.

I'd like to know if there's a way how I can make my HDDs detected.

I'd also like to know if there are other distros than iAtkos to have 10.6 Snow Leopard version, because that's the only one I found.

Thanks in advance,
